Agilent Technologies Inc. announced the world's first fully coded bit error ratio (BER) solution for the time division duplex (TDD) version of 3GPP's long-term evolution (LTE) standard using 2x2 and 4x4 multiple input/multiple output (MIMO) technology. This solution complements Agilent's same capability for the frequency division duplexing (FDD) version of LTE and is expected to accelerate the development of mobile devices and base stations for the China market.
The solution is built around Agilent's 3GPP LTE Wireless Library (W1910/E8895) and its MXA Signal Analyzer to help wireless-systems designers and verification engineers speed development of evolving TDD-LTE designs. TDD-LTE is playing an important role in markets where unpaired spectrum is a requirement -- particularly in the China mobile communications market. The library, which is based on Release 8 of the 3GPP standard for the next generation of mobile communication products, provides preconfigured simulation setups that support both downlink- and uplink-coded BER, along with transmitter measurements such as spectral emission mask, error vector magnitude (EVM), complementary cumulative distribution function (CCDF) and detailed demodulation analysis down to the sub-carrier and symbol levels. The latest update to this library complies with TS36.211 v8.3.0 (2008-05) and incorporates downlink transmit and receive MIMO models for both frequency division duplex (FDD) and TDD in 2x2 and 4x4 MIMO configurations.
